Frequently Asked Questions


What is the efficiency like?

The efficiency rating which is at 94% and ErP A-rating for heat and hot water make this a highly efficient boiler. This unit has an extra condensed heat exchanger made of stainless steel which greatly adds to the efficiency.

What about the output rating?

This Vaillant boiler has a central heating output of 26.4 kW, making it convenient for larger properties with up to 20 radiators.

Are there other options for the Vaillant Green IQ range?

Yes! Should you have a higher demand for domestic hot water, then there's the Green IQ 627; a system boiler that stores hot water in a hot water cylinder. Additionally, for properties that require larger quantities of hot water, the IQ 835 has a 43-kW combi boiler available.

Can I use a combi boiler in my home?

Of course! Combi boilers are popular among homeowners in the UK because they save space and don't require additional components. However, if you have more than 2 bathrooms or a high demand for hot water, a system boiler will likely suit your needs better.

Any distinguishing cCharacteristics of the IQ 835?

The Green IQ 835 is a low-maintenance boiler with impressive peak performance. That level of energy efficiency makes this unit easy to rely on and has a green mode that can optimize cycles that result in even lower consumption of gas.

The components are also run by its high-tech control system which keeps them all optimized. It's 85% recyclable when it is time for replacement so you can trust that this product will be used well into the future.

What is the warranty like?

With a 5-year assurity, this IQ 835 can be extended to 7 or 10 years. All you need to do is getting registered by an Advance Vaillant Installer.
